ROLLER- FRAME.

SPECIFIGATION forming part of Letters Patent No. 755,055, dated March22, 1904.

Application filed September 8, 1903- citizen of the United States,residing at Bristol, Hartford county, Connecticut, have invented certainnew and useful Improvements in Roller-Frames, of which the following isa clear, full, and exact description.

My invention relates to an improvement in roller-frames, particularlysuch as are designed for placing upon the bottoms of trunks and otherlike articles. 7

The object of my invention isto simplify, cheapen, and improve theconstruction of such devices, and particulary to stiffen and strengthenthe ears to resist lateral strains.

My invention will be defined in the claims.

The accompanying drawings illustrate my invention embodied in simple andpreferred forms.

Figure l is an end elevation of one form of my device, showing theroller in place. Fig. 2 is a side elevation of the same device, alsoshowing the roller. Fig. 3 is a bottom plan view of the same device, theroller being omitted. Figs. 4 and 5 are respectively a' sectional endand a side elevation of a modified form of device, the section of Fig. 4being on line 4 4 of Fig. 5. Fig. 6 is a top plan view of the same formof device.

I will first describe the construction shown in Figs. 1, 2, and 3. Thisroller-frame is preferably but not necessarily formed out of a sheet ofmetal which is out to proper form and the parts bent and struck up intothe desired shapes. This frame has a base-plate B, from which extenddownwardly roller-ears E and E, one .at each side of the base andpreferably centrally located relative to the length of the base. Theseroller-ears are preferably formed from metal which formerly extendedoutwardly from the sides of the base-plate that is, they are preferablynot cut out of the base, although one of these ears might be cut fromthe base, if desired, and both of them might be if the base weresufiiciently broad to accommodate their lengths. Theconstruction shownis, however, the one preferred by me. Each of these roller-ears near itslower end is provided with a hole 6, adapted to receive the journal ofthe roller R. Two small Serial no. 172,220. (No model.)

securing-ears C are shown as extending upwardly from one edge of thebase and at each side of the roller-ear E. Preferably from the oppositeedge of the base extends upwardly an arm A, which is preferablyconsiderably greater in size and extends much higher than the ears C.The roller-ear E upon this side of the base is preferably cut from thelower portion of the arm A, forming the hole 6', as

clearly shown in Fig. 2. This arm A and base-plate than are the edges ofthe ear; but

I do not limit myself in all cases to an inward bend. The bend extendsupward to the baseplate, and the inward bend (shown in the drawings)extends up to and includes a portion of the base-plate, as clearly shownin Fig. 3. This inward bend may obviously take different forms; but Ipreferably dish the whole, or substantially the whole, ear inward, asshown in Figs. 1, 2, and 3.

The form of roller-frame shown in Figs. 4, 5, and 6 differs slightlyfrom that shown in the other figures. In this form the upwardlyextendingarm A and ears C have been omitted, although these might be employed inconnection 'with this form, if desired. These might also be omitted inconnection with the forms shown in Figs. 1, 2, and 3, if desired. Therollerears E of this second form are dished in the same manner as thoseshown in Figs. 1, 2, and 3. In addition they are strengthened by meansof one or more narrow inward bends or corrugations F, preferably formedone at each side of the ear adjacent the points where the edges of theear join or merge with the base. The axes of these corrugations extendacross the line of juncture of cars and base, and consequently include aportion of each, as is clearly shown in Fig. 4. These corrugations ornarrow inward bends materially strengthen the roller-ears whether theears are dished or flat and assist to prevent the bending of the carsfrom their normal position. The structure of the ears and the positionof the corrugations are clearly shown by Fig. 4., which shows theeasterframe in section upon the line 4 4 of Fig. 5.

I am aware that many variations from the constructions shown may be madewithout departing from my invention as claimed, and I therefore do notlimit myself to the particular embodiments of my invention hereindescribed and illustrated.

Having thus described my invention, what I claim' is 1. A sheet-metalroller-frame having a baseplate and a pair of roller-cars integral withand extending downwardly from said baseplate, one or more of said earshaving an inward bend extending up to and forming a concavity in saidbase-plate.

2. A sheet-metal roller-frame comprising a base-plate and a plurality ofroller-ears extending downwardly from said base-plate, said ears havingholes for the reception of a roller-journal and one or more of the earshaving an inward bend extending from its hole up to and forming aconcavity in said baseplate.

3. A sheet-metal roller-frame having a baseplate and a side plateintegral with said baseplate and extending upward at one side of thesame, and a downwardly-extending roller-ear at each of two oppositesides of said baseplate, one of said ears being integral with one ofsaid plates and cut out of the other plate.

t. A sheet-metal roller-frame having a baseplate and aside plateintegral with said baseplate and extending upward at one side of thesame, and a roller-ear integral with one of said plates and cut out ofthe other plate and extending downwardly from said base-plate, andone-or more upwardly-extending lugs on the opposite side of saidbase-plate.

5. A sheet-metal roller-frame comprising a base, a roller-ear turneddown centrally of each of two opposite sides thereof, an arm extendingupwardly from one of said sides and joined to the base on both sides ofthe rollerear, and one or more cars turned upward from the opposite sideof the base.

6. A sheet-metal roller-frame comprising a base, a roller-ear turneddown centrally from each of two opposite sides thereof, and an armextending upwardly from one of said sides and joined to the base on bothsides of the rollerear which is located on that side.
